Run Wii ISO's Off of a USB Stick?

Hey guys, I just followed the tutorial on how to get the homebrew channel and now I have everything I need to be able to play ISOs I think... I was just wondering if someone could direct me to a place where I can learn to play ISOs off of a USB stick? My friend has something called the Disk Channel where he plays all of his games there off of a USB stick...

reccommend a usb external HDD as USB sticks will not hold many games,
You will need wbfs manager to format (any drive,sd,usbstick,
Wii ISO
and a USB loader toad load the games from the USB drive on the wii
